"Can you love more than one person?" A lot of conversations about nonmonogamy start this way. When we discuss "opening" relationships, contemplate whether we want to be exclusive with our partners, or introduce multiple partners to friends and family, we are asking the people in our lives, and ourselves, to contend with this question.

The answer is obvious, and misleading. The love one feels in their heart and the love one expresses through daily acts of care and affection are both "love" in the true sense, but they have different requirements, present different options and produce different outcomes.

More Than Two, Second Edition, can't promise outcomes, but it is a guide to the paths--from anchor or nesting partnerships to relationship anarchy--possible within nonmonogamy. This long-awaited second edition bridges emerging theories on attachment and relationship diversity with authors Eve Rickert and Andrea Zanin's insight and experience. The arcs of nonmonogamous partnerships bend towards complexity, introspection and compromise--or at least they can, if we work at it.
